Include Namespace Support for InfluxDB 2 Helm Chart

[TotomiEcio]

Description:
Hello,

I have been working with the InfluxDB 2 Helm chart and noticed that it currently lacks support for specifying a namespace. I believe adding this feature would greatly enhance the flexibility and usability of the Helm chart.

Proposal:
I propose adding the following configuration option to the InfluxDB 2 Helm chart:

namespace: {{ .Release.Namespace | quote }}

This would allow users to easily deploy InfluxDB 2 into the desired namespace, aligning with the practices of other Helm charts such as Kafka and Postgres.

Examples:
Here are some examples from other Helm charts that demonstrate the use of a namespace parameter:

• Kafka: bitnami/kafka/templates/broker/statefulset.yaml
• Postgres: bitnami/postgresql/templates/serviceaccount.yaml

How I Can Help:
I would be glad to assist with the implementation process.

Thank you for considering this proposal. I look forward to contributing to the InfluxDB 2 Helm chart and improving the user experience.

Best regards,
Tomas
